PORTABLE DEVICE FOR UNLOADlNG CARS.

sPEcIFicATIoN forming part of Letters Patent No. 536,209, dated March26, 1895.

Application filed February 1, 1894:. fierial No. 498| (N modem To allwhom it may concern:

Be it knownthat I, GEORGE H. HUL TT, of Cleveland, in the county ofOuyahoga and State of Ohio,have invented certain new and usefulImprovements in Portable Devices for Unloading Cars; and I do herebydeclare tlie following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same. 7

My invention relates to an improvement in portable devices for unloadingrailroad cars,

and is designed more particularly as an improvement ,on the constructiondisclosed in my Patent No. 516,053, granted March 6, 1894:.

My present improvements consist more part1cular1y in improved means foroperating the discharging trough through which the coal or othermaterial is discharged; in means for removing the end or end gate of thecar, and in means for preventing the coal or other material 'fromfalling out at the sides during the operation of tilting the car.

In the accompanying drawings,Figure 1 is ayiew in side elevation of myimproved device showing a car thereon, the cylinders and plungers foroperating respectively, the

trough of the platform and end gate of the car, being omitted. Fig. 2 isan enlarged view 0 .of the shorter end of the tilting platform showingthe trough in dotted lines, the hydraulic devices for actuating thesame, and the devices for elevating the end gates of the cars theoperators cage'being omitted. Fig. 3 is 3 5 a view in cross section ofthe tilting platform showing the trough therein, and Fig. 4. is atransverse sectional view of the shield.

A represents a railway constructed to receive the truck B, which latteris mounted on 0 wheels 0 arranged in pairs and is adapted to travel backand forth parallel to the pier or water front, as shown, or parallel tobins or,

other repositories designed to receive coal or material usually carriedin bulk. The wheels 5 C are asstated arranged in pairs, each pair 1constituting in effect a truck, the trucks so formed being pivotallyconnected to the main truck B, so as to enable the wheels to followinequalities in the track without straining the parts. This truck Bisprovided on its upper face with a bearing or way for the rollers D,which latter are carried by the ringE. Resting on the rollers D, andsecured to the truck by a suitable king. bolt or equivalent device isthe rotary platform F, which latter carries a suitable engine andboiler, or electric or othermotors-for actuating the drums and othermovable parts. The platform is rotated by means of the rack and pinionordinarily employed for that purpose, and is provided with the uprightsF and G, the former being considerably longer or higher than the latterand connected thereto by the braces G, G

The two shorter uprights G are connected together at the tops and atintermediate points if desired, while the uprights F are also connectedat their tops by the braces G Pivotally mounted on the upper ends of theshorter uprights G is the inclined platform H, which latter consists ofpreferably two paral- 7o lel girders G (see Fig.3) located a properdistance apart and connected at intervals through their length, formingin effect a plat-- form. The platform thus formed is provided withrails, G (see Fig. 1) and is beveled at the 7 5 end of its longer arm(not shown) so that when in position the beveled ends of the rails willrest on the rails of the surface track and forma continuation thereof,sothat a car on the surface track can, by the mechanism to be hereinafterdescribed, be drawn up the inclined platform to the position shown inFig. 1, discharged of its contents and lowered onto the same or ontoanother track.

The platform H is pivotedlto one side of the 8 5 center, and is providedat its outer or shorter endwith a bumper or buffer I and adjacent to thelatter is the mouth of the discharging chute J. The chute J is open atits bottom, and discharges directlyinto trough J the shape of which isclearly shown in Fig. 3. This trough is open at its topand is providedwith flanged rollers a at intervals along both sides of its bottom whichrun on the flanges b of the angle irons c constituting parts of the 5girders, and is provided on its opposite-sides near its upper edge'withflanged rollers d which are designed to move in contactwith the loweraces of the'angle irons c also constituting parts of the girders.

Secured to the under side of the trough are the plates 6, to which issecured the free end of the plungerf. This plunger is carried by thehydraulic cylinder 9, which latter is supported at intervals by thebeams h secured to the under side of the girders which constitute thebody of the tilting platform. Water un der pressure directly from pumpsor from an accumulator (not shown) on the rotary platform is conveyedthrough flexible or telescopic pipes or by any other of the well knownmeans in common use to the cylinder 9 at a point in front of the plungerhead, and operates to govern or control the outward movement of thetrough, hold it in any desired position and restore it to its normalposition within the tilting platform as shown in Figs. 1 and 2. Ifdesired, water can also be introduced behind the plunger head so thatthe trough can be forcibly pushed out in the event of clogging or if theweight of the coal should be insufiicient. After the platform has beentilted and a portion of the coal or other material discharged into thechute and from the latter to the trough, the Weight of the coal tends toforce the trough outwardly. Hence by releasing the water in front of theplunger the trough will descend by gravity and can be stopped by simplyshutting off the water, and elevated by admitting water under pressure.In this device, as in the patent hereinbefore referred to, the trough isprovided with gates at its end and one in its bottom through which thecoal can be discharged, the gates when open acting as deflectors for thecoal.

Located under and carried by the the tilting platform is a secondhydraulic cylinder 71. (see Fig. 2) the plunger of which is connected tochain 2'. This chain z passes along the under side of the tiltingplatform to the sheavej and from thence up to the small winding drum kon the operators cage Z. This drum is carries two larger drums m aroundwhich chains 11 are wound, the chains 1, and n being passed around theirdrums in opposite directions so that when one is wound the other willunwind and vice versa. Chains n carry hooks or other devices forengaging the end gate of the car for elevating same.

Water under pressure is admitted on both sides of the plunger head incylinder h, and is conveyed to said cylinderthrough flexible or otherpipes, and the movements of this plunger and also the plunger whichactuates the trough are under the control of the operator located incage Z. By admitting water to both sides of the plunger head in cylinderh chains n carrying the gate hooks can be elevated or lowered at thewill of the operator.

The operators cage Z is located at the outer end of the shorter arm ofthe platform in a position over the chute. Pivoted t0 the operators cageat the point a, or at the top of the buffer is one end of the shield orframe P, the opposite end being supported by rods 0 which engage thegirders G2 as shown in Fig. 1, thus leaving the shield free toaccommodate itself to the top of the car and supporting the shield whenthe car is removed. This shield P is designed to occupy a position abovethe car and is preferably open on top, the two sides or two frames beingconnected by yokes 19. These frames form in effect continnations of thesides of the car, and prevent the coal from rolling off at. the sideswhile the car is being tilted.

The trough directs the coal or other contents of the car to any part ofthe hold or bin, and the gates at the end thereof are actuated by ropesor chains under the control of the operator whereby the discharge can beregulated both as to quantity and direction.

After the car has been discharged of its load, the platform is tilted soas to carry the end thereof well out of the hold or bin, and the rotaryplatform is then turned so as to bring the beveled end of the tiltingplatform over a track onto which the empty car is to be run. Theplatform is then lowered onto said track and the empty car lowered,after which the platform is turned to the track having the loaded carsthereon, and another one carried up and discharged as described.

Lisa hydraulic cylinder pivotallyorloosely mounted on truck B andprovided with a plunger, the free end of which is connected to thetilting platform as shown. By means of this plunger and suitable meansfor forcing water therein the tilting platform can be tilted from theposition shown in Fig.1 so as to bring the discharge end well down overthe boat. By permitting the water to escape from the hydraulic cylinderthe opposite end of the platform is lowered onto the track.

The platform H is provided with a sheave H, around which passes chain M.The free end of this chain is adapted to be attached to the car coupler,while the opposite end thereof is secured to drum N after passing aroundsheaves N N. Thus when the platform is in the position shown in Fig. 1,and the chain M attached to a car the rotation of the drum N which isactuated by a suitable motor causes the car to move up the incline untilit comes in contact with the buffer. The drum is then looked againstrotation, and the platform tilted by the mechanism previously described.

By mounting the tilting platform on a truck .the entire apparatus can bemoved lengthwise the vessel so as to bring the discharging end thereofover the several hatchways, thus permitting the entire cargo to bestored without shifting the boat.

Instead of employing hydraulic devices for tilting the platform chainscan be employed.

I would have it understood that I do not confine myself to details ofconstruction, but consider myself at liberty to make such changes andalterations as fairly fall within the spirit and scope of my invention.
